I'm working on a business idea where I plan to develop a web-based application for a specific industry. I would like to offer this application with a hosting service on my own server (which I currently don't have yet).
Since I mainly will be hosting my own products (I also would want to sell hosting packages), I don't plan to offer support for a wide variety of platforms and scripting languages.
Since I'm on a limited budget, I will have to choose an option that wouldn't require large expenses on software licences and so on.
Can anyone suggest a platform(s) and scripting languages that would suit my case?
Also, how can I minimise the cost for hardware equipment? And exactly what do I need anyway?
